Record and manipulate images recorded from the front/back camera.
There are several simple graphical blocks that allow students to process camera frames, such as get_frame, to_grayscale, get_blobs etc.
The video below shows how to attach blocks together in order to get an object detection preview running
Extract location information of a pendulum
In order to track the X position of an oscillating pendulum, we use the object tracking to locate its position, and add the coordinate to a timestamped list
Following the data acquisition process, we plot the acquired data, and also fit it in order to extract the frequency.
